To all w/wm 'it may concern Be it known that l, F RANK RIDLEY PIPER, la citizen of the United States, residing at Fairfax, in the county of Chambers and State of Alabama, have invented certain new and useful Improvements in Rollers, of which the following is a specification.

My invention relates to improvements in the construction of rollers used in machines for operating upon threads or strands of material during their treatment in a liquid vat.

In the machines in common and general use rollers of wood are employed, and it has been found by long experience that such rollers have a short life, making their use expensive, also that their surface may not wear evenly, also that their use causes a loss of time and delay for adjustment and replacement, and further that it is a diflicult matter to make wood rollers of the proper size and desired surface.

The main object of my invention is the production of a roller which will entirely overcome all of the objections and defects known to exist in the wooden rollers in use, and to providev a roller which will practically last a life time,` which will permit the instant application of a contact surface forming a perfect substitute for wood to meet all requirements, which will be of simple and durable construction and capable of production at a comparatively low cost, thus insuring an eflicient, desirable and thoroughly practical substitute for the wood roller.

The invention broadly stated consists of a roller consisting` of a metal roller or core and a detachable contact surface wound upon and forming a cover around the metal roller.

The invention further consists of a roller of the charact and for the purposes stated embodying novel features of construction and combination of parts substantially as shown, described and particularly defined by the claims. A

In order that the construction iu detail and the operation of my invention may be understood and its many features of merit and advantages be fully appreciated, I invite attention to the accompanying drawings in which:

Figure l is an end view of twin rollers constructed in accordance with and embodyingrny invention, showing the relation of the rollers in use,

Figure 2 is a side view of one of the rollers with the helical covering removed,

Figure 3 is a similar view with the helical covering wound upon the body or core of the roller,

Figure 4 is a detail sectional view of one end of the roller, showing the construction of the end heads or caps and the manner of shrinking or threading them on the hollow roller as well as the manner of clamping the ends of the rope or helical covering.

Figure 5 is a detail view of a modification.

The invention is of extremely simple construction and consists of the hollow metal core or body A, the caps or heads B, of somewhat larger diameter than the core and formed with a rim C, shrunk or threaded into the ends of the core, and further formed each with a hub D, provided with an opening E, to receive the through shaft F, whose ends project the required distance.

This construction provides a hollow metal roller with flanged caps or heads and upon the roller and confined and retained by the flanged heads is the coiled or helical covering (l, preferably of cord or rope of the desired size and material and wound as shown with each end of such helical. covering` passing through an opening H. at each end of the roller and through the yoke clamps J, which by reason of the nuts K, act to securely fa sten the ends L of the helical in place, and also allow the removal of such helical cover when found necessary.

lt will thus be seen that my iuvcutimi provides a substitute for the wood rollers now in use, which will prove a great saving in time, labor and expense; which will permit with ease and facility the application or removal of the 'Contact surface or covering; which will permit the use of various sizes of spiral covering as well as of any suitable material, land which generally will provide a roller construction which will commend itself as thoroughly efficient and p ractieal.

The invention may be used for any purpose-where it would function properly but is particularly useful, etlicient and desirable in cotton mills for cleaning or bleaching the continuous strip of material producing towels and the use of a covering of coiled material such as rope or cord of the proper size is desirable as such a covering exerts the proper pressure or rubbing action against the Strip as t@ @Eea a much better Cleaning oi said strip than a roller made oft' Wood, rubber or in fact any other character of material.

l. A roller for use in textile machines, consisting of a metal core or roller, and a removable covering for said roller, said roller having means for confining and retaining said covering in place.

2. A roller for use in textile machines, consisting of a metal roller, and a helically Wound covering for said roller, said roller having a flange at each end to conne the covering in proper position.

3. A roller for use in textile machines, consisting of a metal core or body, a cover ing wound around the body, and having its ends free, said roller having means to lconline the covering in place, and means for de tachably securing the said ends to retain the cover upon said body.

4. A roller for use in textile machines, consisting ol a metalvroller, flanged caps connected to the ends of said roller, and a helical covering wound upon said roller and confined by the flanged caps.

5. A roller lor use in textile machines, consisting ot a metal roller, flanged caps secured to the ends of said roller, a shalt keyed to said caps, a helical covering Wound upon the entire roller and confined by said flanged caps, and fastenings engaging and retaining the ends of the helical to secure the covering andito allow its removal.

G. A roller for use in textile machines,

consisting of a core or body, a covering Wound upon said core, and means carried by the 'corelfor confining said covering upon the core. l

7. A pair of rollers Vvfor use in cleaning threads arranged in parallel relation, and a helical covering Wound upon said `rollers to bear upon the threads and fastenings `arried by the rollers for securing the said coverings and permitting removal thereof.

` 8. A pair of rollers for useV in cleaning threads arranged in parallel relation, helical coveringsV uponsaid rollers, and ilanges on the rollers to confine the coverings in propel' place and fastenings carried by the rollers for securing the said coverings and permit ting removal thereof.

9. A pair of rollers for use in cleaning threads arranged in parallel relation, and a removable thread engaging .covering upon said roller and fastenings carried by the rollers for securing the said coverings and `permitting removal thereof.

In testimony whereof I allix my signature.
